The ultrasonic emmi-dent E2 attachment contains a special, patented Piezo-Chip. This is contained within the attachment head and generates the 100% Original emmi-dent Ultrasound.

It is important that you change the ultrasonic attachment after 3 months of use and no later. After this time, the ability of the attachment bristles to effectively transmit ultrasound waves will diminish and therefore optimum dental cleaning and oral hygiene can no longer be guaranteed.
